------- Additional Comments From dean@bong.com.au 2007-16-03 16:10 ------- unreal tournament 2004 has a native port.
unless im mistaken the only major difference is that the windows version has dynamic personalized number plates on vehicles.
so for any readers it is worth looking into the linux native port, ryan gordon has done an excellent job on it. its straight forward to get going in both 32 and 64bit.
that said, this bug most likely extends to other games using the unreal engine without a linux port (for example swat 4, which in fact it does affect)
